An authorisation is required, but I don't know how strictly this is upheld by testing centers. None for the ATP intial though,

OK I stand corrected. You don't need an endorsement IF you have a Commercial/Instrument ticket or ATP. Quote from the FAA:
To verify that you meet the experience requirements of 14 CFR part 63, section 63.37, it is necessary to obtain a written statement and signature from one of the following authorized persons:
• A qualified flight engineer with the appropriate class rating • A U.S. Armed Forces flight engineer instructor for the same class of airplane • A flight engineer instructor associated with 14 CFR part 121 training program • An FAA Aviation Safety Inspector (operations/airworthiness)
The endorser must include a statement that they have personally verified that you meet the experience requirements of 14 CFR part 63, section 63.37. They must also identify their position, such as flight engineer certificate number, name of the training facility, and FAA inspector’s office identification.
The verification of experience requirements is not required if you hold one of the following:
• A commercial pilot certificate with an instrument rating or an Airline Transport Pilot certificate issued by the FAA
• A foreign unrestricted commercial pilot or Airline Transport Pilot license issued by an International Civil Aviation Organization (ICAO) member state
• A passed, failed, or expired original test report for that specific test
